The Michigan Department of Transportation has revised the requirements for Aggregate
Inspection Certification. Beginning in 2013, two different levels of aggregate inspection
training and certification will be offered, Aggregate Inspection Certification Level
One and Aggregate Inspection Certification Level Two. Technicians that are currently
Certified for Aggregate Inspection are eligible to enroll in Aggregate Inspection
Level Two. Technicians that are NOT currently Certified for Aggregate Inspection are
required to complete the Aggregate Inspection Level One training before enrolling
in the Aggregate Inspection Level Two training. Technicians inspecting fine aggregates
or road gravel are required to complete the Aggregate Level One training. Technicians
inspecting concrete aggregates or asphalt aggregates are required to complete Aggregate
Level Two training. Please contact our office by phone; 231-591-5826, or by email; icet@ferris.edu, with
any questions about this change in the Aggregate Certification requirements.

Technicians applying to take the certification courses and examination should have
experience and/or working knowledge of the listed course topics before undertaking
the examination. Basic math skills in the use of fractions, decimals, ratios, and
percentages are also required. The successful completion of Aggregate Inspection Level
One or the Michigan Aggregate Inspection Certification (issued before 2013) is required
before enrollment into the Aggregate Inspection Level Two Training.

This one day training course satisfies the requirements of the Michigan Department
of Transportation and the Federal Highways Administration for technicians involved
in the sampling of aggregates for quality control tests during aggregate production
and placement. This class is only if you need endorsement A. If you are signed up for the Aggregate
Level 1 Re-certification, you do not need to take this class. If you have questions
about this, please call our office, 231-591-5826.

Aggregate Sampling Learning Outcomes Include:

Identify aggregate segregation problems resulting from production and sampling.

Identify aggregate sampling requirements in the Testing Order Form 501.

Identify aggregate sampling techniques according to MTM 107.

Identify and demonstrate sampling procedures used for sampling from a mini stockpile.

Identify and demonstrate sampling procedures used for sampling diagonally from the
road grade.

This three day training course satisfies the requirements of the Michigan Department
of Transportation and the Federal Highways Administration for technicians involved
in aggregate sampling, washing, sieving, and determining crush content of aggregates
for quality control during aggregate production and placement. Level One Certification
is required for technicians inspecting road gravels and fine aggregates.

Successful completion of all learning outcomes for Endorsement A, Aggregate Sampling,
described above.

Demonstrate the field sample reduction of aggregates into laboratory test samples,
22A, 2NS.

Demonstrate MTM 108 test procedures and complete calculations to determine the amount
of material loss by washing, finer than a No. 200 sieve, for 22A and 2NS, using the
manual hand wash method.

Demonstrate MTM 108 test procedures and complete calculations to determine the amount
of material loss by washing, finer than a No. 200 sieve, for 22A and 2NS, using the
mechanical washing method according to AASHTO T 11-05 (2012) paragraph 5.6

Student achievement of learning outcomes will be assessed with written examination,
80% minimum score for passing, and practical examination, 90% minimum score for passing.

Upon successful completion of the above requirements, the Level One Aggregate Inspection
Technician will be certified to perform quality control tests for, aggregate sampling,
sieving, washing, and the determination of crush content for five years.

This four day training course satisfies the requirements of the Michigan Department
of Transportation and the Federal Highways Administration for technicians involved
in determining the deleterious content, flat and elongated content, coarse aggregate
specific gravity and absorption, fine aggregate specific gravity and absorption, un-compacted
void content, and LA Abrasion testing of aggregates for quality control during aggregate
production and placement. The aggregate technician enrolling in this course should
have at least three years of practical experience performing aggregate testing in
a quality control laboratory. Level Two Certification is required for technicians inspecting concrete aggregates
and asphalt aggregates.

The Board of Examiners shall administer an examination for certification. The examination
is composed of two parts:

Part 1 - Open Book Written examinationMinimum Score 80%

Part 2 - Practical examinationThe practical exam candidates must demonstrate their competency in meeting aggregate
testing standards. The candidate is monitored while completing the actual field tests,
using the proper methods, procedures and documentation for the specified aggregate
tests.

Applicants failing any part of the exam will be allowed to retake that portion of
the exam,written or practical. However, if an applicant fails a second time, the entire course
willneed to be repeated. Options for retaking exams will be explained at the notification
offailure. All retests must be completed within thirty days and participants will be
responsible to pay $150 for a written exam retake and $250 for a practical exam retake.

Aggregate Technician Refresher Course and Recertification Test

Recertification is required every five years. It is the responsibility of the practicingtechnician to maintain an active certification. For recertification, the technicianmust pass both a written and practical examination similar in format to the originalcertification tests. Failure to achieve a passing score will require the candidate
to retakethe failed portion of the exam, written or practical. A fee will be charged on all
retests.Failure to pass a second time will require the candidate to attend the entire certificationcourse. If a Certified Aggregate Technician fails to become recertified from thedate of certificate expiration, at a minimum, the refresher course must be taken torecertify.

The refresher course includes a one day review of test methods and a written examination,
followed on the second day by the practical exam. The refresher course gives technicians
an opportunity to review the certification test requirements, and to review updated
MDOT regulations. The refresher course is limited to individuals who have already
received Aggregate Technician Certification. The re-certification course does not
allow sufficient time for technicians to practice test methods and reports. Previously
certified technicians that need to practice test methods before the practical exam
should enroll in the full 3 day course.
